Made My Own ,Large on the Right (Perspex) laser cut 42/43mm other side a Plastic End Cap (Modified)the rest I found different size Grommet's at different hardware stores and Modified to fit, than even had BMW stickers made for the Ends.

I like the Evotech Crash protectors. They are just long enough I can straighten my legs forward and rest my knees for a bit. I know the crash bars would work better though. Cuban Rider's crash video on YouTube is a testament to their function.
